A new approach to cloud detection is introduced that exploits the difference between two solar spectral reflectances as a function of view angle. The resulting band-differenced angular signature is sensitive to the contribution of Rayleigh scattering from above the tops of clouds and can be used to discriminate high clouds from lower level clouds and clear sky. The authors use model simulations to show that this technique could be applied to measurements from the Multiangle Imaging SpectroRadiometer, scheduled for launch on the first platform of the Earth Observing System. Results show the technique to work best over ocean and snow surfaces. Over such surfaces, the minimum detectable high cloud optical thickness (at 0.55 μm) would typically be 0.5 without the use of any a priori scene information, and lower if such information is available
